The use of externai~ fluxifeed to the.cutter, made it possible to simplify the design of the flux feeder and to~employ 6utters used in conventional oxygen cutting of low-carbon steel.;,;.Mor6oier, the use of a cyclone flux feeding device ensured the accurate dosage*6f small amounts of powders supplied to the area of cutting. Speeds of cutting stainless's,teel, attained on the "URMS-11" machine exceed those of the URKhS-3 machine,bi~a factor of 1.8- 2.3; they may be compared to speeds of cutting low-carb'On.steel of the:'swe thickness. The higher speeds are achieved by increased oxygenconsumption without a higher flux consumption, by a smaller width of the oxiaatio'n r~eaction;front, and by the intensified fluxing of oxides.~,The specific'flux consumptionof the URKhS_4 machine was by 2-4 times lower than that of the.'VRXhS_3,machine,due to a finer grain size of the flux (less~than 0.15 mm) and.'a'~bett~Pr.distribil~ion~of the flux over the cutting area. As a result the cost ofimaterial per 1~running meter of cut was reduced by a factor of 1.3-2.- The frarl _~" (VIM)'iron powder of the following composition is recommended for use-on the!.URKhS_2r'machine:- 94_wq6% Fe (total); o-4% C; 1.2% Si;- 0.5% Mn; :0.06% S; 0.05% P. ~The loose weight is 2.1-2.3 g/cm3.

In extremely high-Cr steels the overheated area has a finely acicular structure (photo). The HV hardness of the martensitic la'~er next to the cut edge is 400, increases to 630 at 1.5mm. depth, decreases' to 3 20 at 5 mm: dep th (probably owing to self-anneal), and transits into troostite. Spectrum analysis re- veals a significant alteration of the alloying elements at and.nearlthe cut edge (to 0.3 mm depth), depending primarily on the degree of preheating of the metal prior to O-flux cutting. Analyses made on steels X17 (Khl7) and lX11 (lKhl3) are shown. Cr, Mn, and Si burn out readily; in Mark- 18-8 steels the upper edge is enriched with Ni, the concentration of which diminishes as the cutting jet perietra- tes the depth of the metal. The Ni concentration in the exit zone of the jet amounts to about 55-9516 of that in the parent metal. Preheating facilitate s:.the, burn-out of alloying elements. The resulting change in composition red uces the stability of the austenite in NiCr steels, since the martensite-transformati6n temp Ierature is raised thereby. The causes engendering the change in chemical composition are sought. The iron powder introduced burns up in the 0 stream and raises the temperature,, whereupon: (1) The high solubility of the alloying elements facilitates their.trans- ition from the cut edge into the slag and back; also, the alloying elements in the'; ~s wit higher tem perature, steel transit from regions with lower temperature to region h Card 2/3 Investigations of the effect of oxygen-flux cutting - - S/788 ,/62 /00.0 /004 /OOZ /003 where their solubility is greater. This conclusion was substantiate'd.by cutting two packeted plates conjointly, one of lKhl8N9T and one of CT.3 (St.3). The low- C steel underwent Ni enrichment at the cutting edge. This phenomenon can only be explained by Ni diffusion from the slag. (Z) The abrasive action of the fast-moving flux particles and the removal thereby of the refractory oxide formed on the con-: tact surface. (3) The mechanical mixing in the. cutting zone of the parent metal and the powder with various concentrations of alloying elements and their'strong oxida- tion due to the high 0 excess. Speedier cutting reduces the time of c ntact of Ithe 0 liquid slag with the cutting edge and minimizes diffusional exchanges.' An interpre!, tation of the resulting process as occurring iha two-phase system appears justified by experimental evidence. In view of the impLirment of the ph sic' chemical y 0- characteristics of the metal near the cut edge it 1s recommended that'd 0. 5 mm 6f the material near the edge be removed by grinding.
